What's Happening?
A new method for synthesizing ordered mesoporous metal oxides (OMMOs) has been developed, utilizing solvent evaporation-induced cooperative assembly (EICA). This approach allows for precise control over the synthesis process, addressing challenges such as the hydrolysis of metal salts and the formation of disordered metal oxide crystals. The EICA method involves the use of amphiphilic block copolymers and optimizes thermal treatment through carbon-supported crystallization. This technique enables the creation of OMMOs with varied framework compositions and pore sizes, which can be further modified through pore-wall engineering. The study provides detailed experimental procedures to ensure reproducibility, with applications in chemiresistive gas sensing and electrocatalytic hydrogen evolution reactions.
